SHUTTLE THREADER.

Application filed October 8, 1925. Serial No. 61,284.

To all whom t may concern:

Be it known that I, Louis A. CADORDT, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful' Improvements inShuttle Threaders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in devices for threading the shuttles of looms, and the present disclosure of the invention relates specifically to that type of shuttle threader shown in my U. S. Patent No. 1,542,214 of June 16, 1925. In the patented structure, thread guides formed of wire, were secured permanently to a base member and in case of breakage, could not readily be replaced, usually making it necessary to install a totally new threader even though only a small portion of one of the thread guides should become damaged. It is the primary object of the present yinvention to overcome this diiiiculty, by the provision of a. simple and inexpensive construction, by means of whichthe thread guides. are connected with the base member so that they may be quickly andeasily detached therefrom, in case it is. advisable to substitute another guide or guides. l

Further objects are to make certain minor improvements, which will be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings.

Figure'l is a top plan viewshowing the application of the invention to a shuttle.

Figure 2 is a sideelevation of the threader within a shuttle, the latter being shown in longitudinal section.

Figure 3 is a longitudinal sectional view on the'plane of line 3 3 of Fig. 1.

Figure 4 is a vertical transverse section as indicated by line 4 4 of Fig. 1.

Figures 5 and 6 are perspective views of the wire thread-guiding members and the ably connected. .p

Figures 7 and S are perspective views showing a thread-guiding plate which overlies the wire thread guides, together with a vertical wall which carries this plate and another plate connected to the wall to unvderlie the above-mentioned base member.

they are detachone of the thread `guides from the base Y member.

Figure 12 is a detail top plan view showing the way of disconnecting .the other thread guide from the-base member.

In the drawings above briefly described, B designates a metallic base member a'dapt- ,v

ed for disposition ina shuttle recess R and held therein by a removable pin P. In the construction shown, the base member B comprises a top plate 13 and another relatively kshort plate 14 which contacts with the lower side of said top plate, the two plates being preferably although not necessarily stamped from sheet metal and integrally connected with each other by the folded` portion 15. One longitudinal .edge of the top plate` 13 is formed with an upstanding ear 16 having an opening 17 to receive the pin P, and said plate is formed with a transverse shoulder 18 co-incident with said opening 17, said shoulderbeing adapted to abut the pin to assist in holding the entiredevice rigidly in place. The shoulder 18 is preferably formed by stamping one end portion of the top plate 13 downwardly at the corresponding end of thevrelatively short shown most clearly in Fig. 9.

Two thread guides 19 and 2O respectively, formed of wire', are provided over the base memberB, the general construction of each of these guide members, being substantially the same as that disclosed in the patent above referred to, so that specific description of such construction will not herein be however, the end portions of the guide memf ber 19 are specilically identified at 19El and 19h. Similarly, the end portions of the guide 20 are indicated at 20a and 20h. All of these end portions are connected with the base member B in a unique manner. .It may also vbe stated at this point, that the thread guide plate 14, as

19 includes an eye 19? which is disposed in a vertical plane.v One featurel of improvement is associated with this eye. and henceV thespecioreference thereto.

The plate 14 is formed with a .slot 21 whichis preferably atright angles to one of its longitudinal edges,-said slot opening through said edge and registering with a small notch 22 in the overlying edge of the plate 13. Parallel with and spaced from this slot 21, the base B is formed with a transverse slot, 23 which opens through both of the plates 13 Yand 14:, and leading from the end of this slot, remote from the notched edge of the plate 13, is a slot 24 which is formed only in the lower plate 14. The end portion 2()a of the thread guide 2O is passed downwardly through the notch 22 and is bent laterally as indicated at 25, this laterally bent terminal lying within the slot 21.` 'Ihe end portion 201 of the guide 20 passes through the slot 23 and has its terminal laterally bent as indicated at 26, this lateral terminal being confined within the slot 24. It will be seen that by forming the two slots 21 and 24 only through the lower portion 14 of the base member B, said slots and the. overlying portion of the plate 13, in reality formgrcoves in the lower portionof the base member B. When the member 20 is 4to be detached, the operations shown in Figs. and 11 may be followed. rlhe terminal 26 is forced downwardly out of the slot 24, so that the entire member may be slid transversely of the base member B, in a direction to slide the terminal 25 endwise out of the slot 21 as clearly shown in Fig. 10. Then, the member 2O may be turned .about the end portion 20b as a pivot until its terminal 26 may pass through the slot 23, as will be clear from Fig. 11. A reversal of these steps is ofcourse used when applying the member 20 or when applying a new member to take `its place.

Formed longitudinally in the base member B and opening through both of the plates 13 and 14:, is a slot 27, andspaoed from this slot, is an opening 23 which also passes through both of said plates. The lower plate 14 is formed with a transverse slot 29 leading from the opening 28 and cooperating with the overlying` portion of the plate 13 informing a groove. The end portionl9bo'f the thread guide 19, passes downwardly through theopening`28 and has its i terminal laterally ,bent as indicated at 30 for seating within the groove 29. The other end portion 19a of the guide.19 enters the slot 2.7 and has ,its terminal laterally bent as indicated at 31, for, disposition 'in said slot 27. By angling the member 19 with respect to fthe base member B, substantially as shownin Fig. 12, the terminal 30 may be passed downwardly through the opening23 `and 'the terminal 31 engaged with the slot 27, the member 19 being suiiiciently resilient fto yield and overcome any slight binding which might talreplace. `With equal ease, the thread guide 19 may be detached from the base member, so that another may be substituted if desired.

A vertical wall 32 `is disposed in contac withthe outer fside of the ear 16 and is formed with an opening registering with the opening 17 to receive Joined integrally to or otherwise connected with the lower end ofthe wall 32, isa horizontal plate 34C which underlies the base member B and retains the terminals 25, 26, 30 and 31 Within the pockets, Vgrooves or slots of said base member; This plate 34 thus co-operates with the plates 13 and 14 in forming a com posite base whose component parts anchoi` the projections on the ends of the thread guides 19 and 20. i

Projecting` horizontally from the upper end of lthe wall 32 is a thread-guiding plate which overlies the thread guides 19 and 20, said plate 35 being provided in its lower side with a groove 36 snugly receiving the upper portion ofthe eye 19C, yso as to effectively hold said eye in upright position. Moreover', by having the plate 35 lie upon the eye 19C, the lateral terminal 31 of vthe thread guide 19, is retained within the slot 27 and cannot accidentally move therefrom. To form the groove 36, the plate 35 preferably has an upwardly stamped portion 38. For reinforcing purposes, this plate may be formed with integral ilanges 39 wherever advisable.

The thro-ader as a whole functions in the same manner as that disclosed in my prior patent, above mentioned.` It will be seen however that when the pin P is withdrawn and the entire threader is removed from the shuttle, its parts may be readily separated, sothat any worn or injured parts may be replaced, quickly and with ease.

Excellent results have been obtained from the details herein disclosed, for which reason they are preferably followed. However, within the scope of the invention as claimed, modilications may of course be made.
